Kingsport, TN Rides?

I'll be going to Kingsport, TN on business for a couple of weeks in June. I'm planning on taking my folding road bike. Would like to get in some morning/evening rides before/after work, about 15 miles. Also looking for something around 50-60 miles for the weekend. Hills are welcomed and encouraged. Any suggestions?

I do not recall the website right now but you can google "kingsport bicycle association" and their website has a whole list (with cue sheets) of local rides. Also, they tend to do a short ride on Tues and Thursday around 6 PM in the Summer. They also do an organized longer ride on Sat and Sunday during the Summer.

Lots of great roads there, too. Velo Vol's Roan Mtn suggestion is great. Shorter rides should not be hard to find, but watch out for nice rural roads that have been turned into congested suburban roads without improvements (not that that is unique to Kingsport).
